APPARATUS FOR THE MECHANICAL CLARIFICATION- OF FLUIDS- Specification ofLetters Patent.

Patented Jan. 1, 1907.

Application filed April 2. 1906. Serial No. 309,558.

To ctZl whom it nearly concern:

.Be-it known that I, WALTER ROTTMANN, a citizen of the German Empire,and a resident of Berlin, Germany, have invented certain new and usefulImprovements in A paratus for-the Mechanical Clarification of luids, of

which the following is a specification.

My'invention relates. to an apparatus for the mechanical clarificationof fluids; and the special object of the same is to eliminate par ticlesof mud and other foreign bodies horn.

feed-water for boilers and 'water' for other industrial purposes. Thewater may be. conveyed to the apparatus in a natural state or afterbeing previously treated with chemicals. The clarification is. effectedby first conveying the water to be clarified in a bow downward and thenupward. This process can be repeated several times in the apparatus. vWhile the Water sinks or rises in a strea1n the suspended particles areat the same time gradually turned out of the vertical sinking movementand forced to move in the opposite direction. My apparatus, has thespecial advantage that the formation of whirls on the liquid to beclarified passing through the apparatus is entirely avoided and thatconsequently the mud above the collecting place or places cannot betossedor lashed up. I attain this by the, apparatus shown on theaccompanying drawings in three forms of construction, which in each caseconsists of a horizontallyarranged outside reservoir of a cylindrical orsimilar cross-section, which is divided into several compartments by oneor several reservoirs also arranged horizontally in the sarne v Theinner reservoirs are, fastened by means of rivets to the outsidewalls ofthe" outer reservoir and may be arranged in different ways. The fluid tobe clarified enters from above into the space between the outer andinner reservoir and traverses the same in a'desil'ending and ascendingbow. It thereupon passes into the inner cylinders and, if

necessary, a filtering device, whereupon it isconducted to 1 he placeOft'ODSlllllPt-lOIl.""

Fig. 3 shows in adiagrammatic view the cross-seotion of an apparatus formed by threecylinders, one inside of the other. The

Fig. 4 shows a crosssection, and Fig. 5 apartial longitudinal section, through an apparatus in which two innercylinders are arranged in the outer cylinder, but not the one inside ofthe other. Fig-.

Similar numerals refer to similar parts throughout the several views. Y

' According to Figs. 1 and 2, 1 is the outer cylinder, which. is closedon both sides by the To the walls 2 and 3 is riv- This inner cylinwalls2 and 3. eted the inner cylinder 4. der 4 lies eccentric to the outercylinder land surrounds a filter 5 of any construction. In the upperpart of the inner cylinder 4 is an opening 6, through which the fluidpasses from the outer into the innercylinder and through the filter 5 tothe outlet-socket 7. The outer cylinder 1 is at the bottom in the bay 8provided with an opening 9 for letting the mud out! The opening 9 isclosed b the 'lid 10, which can be moved by means 0 any suitable device.This device consists, according to Fig. 6, of a lever 11, which is at 12movably fastened with one end to the outer wall of the cylinder 1. Atthe other end it engages with the slot 13 the bolt 14 of the lid 10.

15 is a frame which encompasses the lever 11. In the frame pivots at 16the screw 17, with the hand-wheel 18. This screw 17 can be screwedforward and backward in the bent piece of metal 19, which is fastened tothe 'wall of the reservoir 1. By turning the screw 17 the lid 10 can bemoved away from the opening 9 or pressed upon it while it turns on itspivot 20.0n the reservoir 1.

21 is an india-rubber packing by which a tight closure is effected.

From the outer wall of the inner cylinder 4 branches off toward the bay8 the wall 22, which serves to conduct the particles of mud into the bay9, through which theinud is let Also the, slanting wall 23 of the bay 8serves to let the mud out.

Inthc space bet-ween the outer reservoir 1 the horizontal wall 24 andthe verticalwa 25, a chamber 26, into which the fluid to be clarified isconducted through the pipe 27.. The Walls of the chamber 26 serve toseparate "I oo the opening through ,which the fluid enters into the-.outer space 28 from the opening 6, through which it leaves it.

29 is a reservoir in which the fluid to be clarified is mixed withchemicals. p 30 is an apparatus serving to prepare the chemicals to beadded to the water, which are conducted to the, mixing-reservoir 29, inthe form of. a solution; through the pipe 31. 32 and 33 are likewisereservoirs for chemicals which are conducted to the mixin -chamber 29through the pipe 34. It is further known that for the chemical treatmentthewater to be clarified is previously heated. To this end steam isconducted in. the apparatus shown in the drawings through the pi e 35into the chamber 26. The water, mixer with the chemicals, falls at 36from the reservoir 29 into the chamber 28, in which the mechan icalclarification. commences. The float 37 automatically regulates in theknown man-' ner the admissionpf thefiuid to be clarified by means of therods 38 39 and the valve 40.

In the inner reservoir 4 there is likewise provided an outlet 41 for themud,twhich can in the same way be closed by a lid, as the abovedescribedoutlet 9. The outlet may, however, also'be of-a different construction.

. 42 is an opening through which the fluid can run over in case theautomatic regulating device for admitting the fluid to be clarifiedshould fail to wor The filter 5' v lid 43 of the outer reservoir 1, sothat it can be easily taken out; but the same can also be cleaned bycausing the fluid to be clarified to enter into the apparatus intheopposite direction. For this purpose there isinserted into theoutlet-pipe 7, at 44, a. three-way cock of a known construction fromwhich a i e 45' leads to the conduit 27 for the raw water. In the pipe45 is arranged a valve 46. Ordinarily the three-way cook 44 acts in away that the clarified water passes from the filter 5 into the outlet 7;but the three-way cock 44 can also be turned in away that the outlet 7is closed, and the filter 5 is, after opening the valve 46, directlyconnected with the raw-water conduit'27 through the pipe 45. The rawwater then passes in the opposite direction through the filter, wherebythe lat- "ter is cleaned. The water entering in this way into theapparatus can at once be let off through the outlet'41 for the mud.

' The eccentric arrangement of the inner cylinder in the outer cylinder,as shown in Fig. 1, has for its resulta narrowing of the cross-section,and in consequence of the same an accelerated streaming down of thefluid to the collecting-place for the'mud. On the other side, however,the cross-section is enlarged. The speed of the water'i's therebylessened and in this way the depositing of the still-ascending particlesof mud facilitated.

is fastened to the removable. I

which closes the mud-outlet and may be of In .the form'of constructionaccording to Fig. 3'-the fluid to be clarified is forced to make alonger way in order to be able to effeet a sure elimination of theparticles of mud. To this end three cylinders are arranged one inside ofthe other. The construction of the outer cylinder'l and of the middlecylinder 4, as well as of the other parts, is the same as abovedescribed. The

The form of construction according to Figs. 4 and 5 is specially suitedfor very large apparatus. The outer reservoir llS dn this case of thecross-section shown in Fig. 4. To its walls 2 and 3 are'riveted theinner cylin drical reservoirs 4 and 47 at some distance l'romeach other,in which are arranged the filters 5, to which the fluid to'be clarifiedpasses through the openings 6 of the cylinders 4 and 47 The chamber 26rests onthe two inner cylinders 4 and 47 and is riveted to their walls.The inner cylinders 4 and 5 are o provided with outlets 41 and 52 forthe mud.

The place where the mud collects in this case in the outer cylinder 1 isat 53. 54 isa slide the usual construction. The fluid to be clarifiedenters in this case into the clarifying device, properly speaking, onboth sides of the chamber 26 at 36 and moves between the wall of theouter reservoir 1 and the mantles of the cylinders 4 and 47 in the firstplace toward the space 53, where the mud collects, from where it entersthrough the openings 6 into the filtering-spaces or the cylinders4 and47.

All other parts'of the apparatus may be of the same construction asshown in Figs. 1 and 2. In this form of construction there is, however,also shownin which way the admission of the chemicals to the chamber 26from thereservoirs 32 and 33 is automatic ally regulated. The float 37,which actuates by means of the rods 38 and 39 the valve 40 of theraw-water conduit, turns at the same time the shaft, 55, which isconnected to the cock 56 of the conduit 34 for the chemicals.

If a float descends, the valve 40 andthe'cock 56 are opened at the sametime, so that a; larger quantity of raw water as well as largerquantities of chemicals can enter. level of the raw water rises; andconsequently also the float, the actionisthe reverse.
